LEWA ecosmart pumps: For simple metering tasks ...

LEWA ecosmart: The clever idea for plant engineering.Solid technology at an attractive price.

LEWA ecosmart pumps:The innovative, compact and mul-tiplex capable diaphragm metering pump in proven quality. For pres-sures up to 80 bar and flow rates up to 300 l/h at temperatures up to 120C.

The diaphragm metering pump LEWA ecosmart offers the best price-performance ratio in its class and meters the often costly fluids with very high precision. As a posi-tive displacement pump, it works with high efficiency.

LEWA ecosmart also excels with its dimensions: No other metering pump of this class has a more com-pact design. In plant engineering, aggregates with a compacted foot-print are appreciated, as the space for the installation of devices and systems is becoming increasingly more scarce and expensive.

Small, modular systems allowing the operator to flexibly adapt his capaci-ties to changing demands or market developments are often the better alternative to a large system geared to one single product only.

Here the LEWA ecosmart metering pumps are recommendable as an economic solution: The low costs of purchase and operations are as convincing as the robustness and longevity of the pumps.

Options Customized valves Various connection geometries Special materials, e.g. PVC

Integration into process control systems via analog and digital signals using Electrical stroke adjustment

Frequency converter Multiplex capability

As single drive unit with space-saving vertically installed motor

Multiple drive units with identi-cal or different output can be combined, e.g. for higher output, pulsation reduction or recipe metering

Water processing, drinking water purification and industrial water conditioning are among the fields of application for LEWA ecosmart.

3Typical fields of application for LEWA ecosmart diaphragm metering pumps:

Water treatment in power plants Metering of additives in industrial water processing

pH adjustment Dosing of solvents in the chemical industry

Feeding of corrosion inhibitors Dosing of colorants and flavors in the food industry

Additive metering in the plastics industry

Injection of chemicals in the oil & gas industry

In all these fields of application, LEWA ecosmart pumps meet the highest requirements: They pump and meter safely, economically, precisely and reliably, independent of the tasks in a wide variety of fields.

Safe: The sandwich diaphragm design with diaphragm monitoring ensures absolute leak-free use. LEWA ecosmart reliably reports any damaged diaphragm. Yet the pump remains leak-tight, and operations can continue for a certain time. A pressure relief valve in the hydraulic system of the pump head prevents potential overload situations of the pump. In LEWA ecosmart, it is individually adjustable.

Economic: Already in purchase LEWA ecosmart pumps have an even more convincing price. The low life cycle costs are based on the high overall efficiency with low energy costs. A minimum of maintenance underlines the operating efficiency.

Solid: The PTFE sandwich dia-phragm, the Diaphragm Protection System (DPS) and the optimized check valves are from the proven LEWA program.

A typical installation of LEWA ecosmart pumps: Upstream processes in the oil & gas industry.

In spite of the standardization, indi-vidual configurations are optionally possible, such as offshore paint, material test certificates and testing according to API (American Petro-leum Institute).

5For each of the four sizes of LEWA ecosmart, there is an appropriately dimensioned PTFE diaphragm in safety sandwich design.

Proven in practice in LEWA quality Reliability of the components is an essential factor in process safety. Practice-tested developments form the basis. LEWA ecosmart pumps are based on well-known and solid LEWA technology. Therefore they have no problems complying even with the rigid guidelines of API 675 (American Petroleum Institute). Cru-cial components of the proven LEWA program are used such as the PTFE sandwich diaphragm with diaphragm monitoring, the patented DPS and optimized check valves.

Diaphragm protection system (DPS): When running diaphragm pumps, leak-free use and operational safety are mandatory, even more so for fluids which are hazardous, abrasive,

pollutive or sensitive. To keep stress on the diaphragm as low as possible, in LEWA ecosmart the diaphragm is driven hydraulically. In combina-tion with the diaphragm protection system (DPS), long service life of the diaphragm can thus be ensured.

Diaphragm monitoring: Any damage to a diaphragm is reliably reported by the diaphragm monitoring system. The safety sandwich design allows to continue operations of the pump up to a scheduled standstill

without any problems. The necessary diaphragm change is very easy to handle.

Optimized check valves: Operations safety and risk of failure essentially depend on check valve quality. Hence the design of the valves is adapted to the individual application. Our dec-ades of experience help us to always find the optimal solution.

Linear stroke adjustment at the hand wheel in stages of 0.05 mm is possible both at standstill and during operations.

By default, LEWA ecosmart is provided with diaphragm monitoring.

For LEWA ecosmart, standard drives according to IEC and NEMA are used.

Integrated worm reduction gear with variable eccentric for stroke adjustment.

LEWA ecosmart:Safety. Metering precision. Value for money.

LEWA ecosmart pumps employ the proven variable eccentric design for adjusting the metering rate.

The advantages of thisvariable eccentric drive: Proven principle: Stroke length is adjusted where it is produced at the eccentric. Both at standstill and during operations, linear stroke adjustment at the hand wheel is possible in stages of 0.05 mm

Harmonic movement of the plunger even in the partial stroke range

Different stroke frequencies of the drive units facilitate adaptation to various fluids and conditions

Long service life thanks to solid dimensioning and durable materi-als, oil bath lubrication, weather and surge water protection

The drive system uses three- phase and AC motors; frequency control for speed adaptation is also possible

Simple operation, easy maintenance

Features and advantages of the electric stroke adjustment: Wide voltage input from 90 up to 264 VAC (single phase)

Servo-motor technology for high precision accuracy

Hand operation (hand wheel not moving during automatic operation)

Analog Input signals 0-10V; 0/4-20 mA or field bus

Integrated active feed back signal 0-10 V; 0/4-20 mA

Explosion proof version (optional)

By default, the drive units are equipped with manual stroke length adjustment.

Optionally, LEWA ecosmart can also be equipped with an electric actuator for stroke length adjustment.
